EJECTOR FOR THE SMOKING GASES OF BLAST-FURNACES AND THE LIKE.

Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed March 5, 1912. Serial No. 681,816.

To all whom it may concern:

Be it known that I, ERNST BITTER SCHI- KICH VON VELLEBIT, a subject ofthe Emperor of Austria-Hungary, and resident of Vienna, Austria-Hungary,have invented certain new and useful Improvements in Ejectors for theSmoking Gases of Blast- Furnaces and the Like, of which the following isa specification.

This invention relates to an improved ejector for the smoking gases ofblast furnaces and the like, which is shown on the accompanying drawing,in which- Figure 1 is a longitudinal central section through the same,while Fig. 2 is a section on the line A-B of Fig. 1.

The ejector comprises a tunnel-shaped sleeve 70, which at one side ofits fiat top end is connected at 2' with the exhaust pipe leading thegases into the same. At the top and bottom the sleeve is provided with acentral opening m and a respectively. Into the upper opening a nozzle 0and into the latter a pressure-water supply pipe Z is screwed. Thenozzle is narrowed toward the interior of the sleeve like a funnel andcarries in the middle a core 2), which is pointed toward the pipe Z anddesigned to disperse the water before its escape from the nozzle. Thecore 10 is fixed to the walls of the nozzle by radial webs g, 9 gwhereby the escape-openings r, r, r are formed Said webs serve also forthe dispersion of water and possess at the top the cross-section shownon the left half of Fig. 2 and at the bottom the cross-section shown onthe right half of said figure. The radial webs possess, as shown on thedrawing, ribs 8, s 8 which extend from the top to the bottom of same andwhich serve also for the dispersion of water.

The whole construction of the nozzle has the object to narrow thepassage of the water, so that the water escapes from the nozzle at veryhigh speed and ejects therefore the gases arriving at 2' through theoutlet n with great vehemency.

I claim:

An ejector for the smoking gases of blastfurnaces and the like,comprising in combination a funnel-shaped sleeve with fiat top end and alateral branch therein for connection with an exhaust pipe and providedat the top and bottom with a central opening, a nozzle in the upperopening narrowed toward the interior of the sleeve like a funnel, apressure-water supply pipe connected with the outer end of said nozzle,a core in the middle of said nozzle having a pointed end directed towardsaid pipe, and ribbed radial webs to fix said core to the walls of thenozzle, all for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

ERNST BITTER SCHIKIGH VON VELLEBIT.
